OR后面可以直接用STAY吗 whether.or. 为什么if后面不能or not,whether可以 whether if or not反意疑问句后面是不是一定要加or not.如：问:He cried:You have made a big mistake,haven't you?答：He cried whether you had made a big mistake or not.2.可以用if代替whether吗?（He cried if you made a big mistak or后面一定要用人称的宾格吗 wonder后面是否能跟if和whether 动词后面一定要跟介词吗 if 后面是不是一定要跟will. whether ..or not... whether or not the thing后面加that还是whichThe thing ___ matters is not whether you fail or not,but whether you try or not. whether 后面加了 or not 后,有什么不同?加NOT 有什么作用呀?I don't konw whether he has a dog (or not). 英语中介词后面一定要跟动名词吗?后面可以跟动词原形吗? like后面跟动词,动词就一定要加ing吗?
